[0002] With the rapid development of cities, there are more and more high-rise buildings with special structures and irregular shapes, and attached tower cranes are widely used. As the tower crane rises to a certain height, an attachment device is needed to connect the tower to the building to increase the constraints of the tower steel structure in order to control the calculated height of the tower, thereby enhancing its rigidity and keeping the stability of the tower unchanged. Traditional attached tower cranes mainly use pre-embedded attachment supports, which require the installation of embedded parts during the civil construction process. Not only is the operation complicated and the construction period long, but the embedded parts cannot be recycled, resulting in material waste, insufficient energy conservation and environmental protection, and increased production costs for enterprises; secondly, buildings with irregular shapes will cause the tower crane to be attached to the wall to exceed the maximum attachment distance of the tower crane and the insufficient bearing capacity of the large tower crane to the wall, affecting the structural safety. Therefore, an ultra-long attachment clamp support for the tower crane is urgently needed to solve the above problems. Summary of the invention

The adjusting rod 1 is slidably connected with the slide groove, which enhances the stability of the connection between the adjusting rod 1 and the installation opening 21 and the smoothness of the movement of the adjusting rod 1; The upper part of the installation opening 21 is fixed with a mounting block 22. The limit column 2 and the mounting block 22 are preferably connected in an integrated manner, and the connection strength is greater; The mounting block 22 matches the strip groove 11, and the mounting block 22 The two outer sides and the bottom are in contact with the inner wall of the strip groove 11, at least one end of the mounting block 22 protrudes from the limiting column 2, and at least one plug hole 221 is passed through the side of the mounting block 22 and is located outside the limiting column 2. Under the condition of ensuring the connection strength, in order to facilitate installation and disassembly, each mounting block 22 is provided with a plug hole 221, and the plug hole 221 is consistent in size with the mounting hole 12. The adjusting rod 1 is inserted into the corresponding mounting port 21. The outer wall of the limiting column 2 is welded with a fixing ring 23, which is fixedly connected to the pull rod of the tower crane body through the fixing ring 23; the number of connecting parts The amount is equal to the number of sockets 221, and the connecting piece is installed between the mounting port 21 and the socket 221; four fine-adjustment clamps 3 are provided and are detachably connected to the bottom of the four adjusting rods 1, and the clamping end of the fine-adjustment clamp 3 is located on the inner side of the adjusting rod 1. The fine-adjustment clamp 3 can be fine-tuned, which is beneficial for the clamp support to be stably fixed on the building. The clamping end of the fine-adjustment clamp 3 can be designed into two types, one is a flat surface and the other is an arc surface, so as to be fixed on a square or arc-shaped building. The adjusting rod 1, the limit column 2, the connecting piece and the fine-adjustment clamp are all made of steel.

[0033] like Figure 2 As shown, the connecting member includes a first screw 13 and a first nut 14. The first screw 13 is inserted between the installation port 21 and the insertion hole 221, and the adjusting rod 1 extends from both ends of the first screw 13. Two first nuts 14 are provided and are respectively threadedly connected to the two ends of the first screw 13.

[0034] like Figure 4As shown, a mounting plate 31 is fixed at the middle of the bottom of the adjusting rod 1, and a hole is opened on the mounting plate 31; the fine-tuning clamping member 3 includes a second screw 32, a clamping plate 33 and a second nut 35, the second screw 32 is inserted into the hole, the clamping plate 33 is located on the inner side of the adjusting rod 1 and is fixedly connected to the second screw 32, the second nut 35 is threadedly connected to the second screw 32, the clamping plate 33 includes an arc-shaped clamping plate 331 and a plane clamping plate 332, the selection of the arc-shaped clamping plate 331 and the plane clamping plate 332 is determined according to the shape of the building, and a rubber pad 34 is fixed on the inner side of the clamping plate 33.

[0035] In this embodiment, during the construction process, if the clamp support needs to be fixed on the building, the components in the clamp support are moved to the required position, and then the four adjusting rods 1 are sequentially placed around the building, and at the same time, the end of the adjusting rod 1 is slid into the corresponding mounting opening 21 on the limiting column 2, and the mounting block 22 in the mounting opening 21 is embedded in the strip groove 11 of the adjusting rod 1, and the adjusting rod 1 is moved to make the clamping plate 33 in the fine-tuning clamp 3 fit the building surface, and align the insertion hole 221 with the adjacent mounting hole 12, and insert the first screw 13 between the insertion hole 221 and the mounting hole 12. After the connection is completed, the two ends of the first screw 13 are respectively located on both sides of the adjusting rod 1, and the two first nuts 14 are respectively screwed into the two ends of the first screw 13 until the first nut 14 is close to the outer wall of the adjusting rod 1. According to the above method, the remaining limiting columns 2 can lock the remaining three corners of the clamp support;

[0041] 1. With the use of the adjusting rod 1, the limiting column 2 and the connecting piece, not only the size of the clamp support can be adjusted and can be fixed on buildings of different sizes, but the clamp support can also be disassembled and reused, which reduces resource waste and construction costs;

[0042] 2. The installation and disassembly steps of the hoop support are simple, which is convenient for construction workers to operate. Compared with the traditional embedded attachment support, the construction period is greatly shortened;

[0043] 3. By further providing a fine-adjustable clamping member 3 on the hoop support, the hoop support is facilitated to be firmly fixed on the building, thereby improving the safety of construction and effectively solving the problem that the tower crane attachment to the wall exceeds the maximum attachment distance of the tower crane due to special-shaped buildings and the insufficient bearing capacity of the large tower crane attachment to the wall affects the structural safety;

[0044] 4. Depending on whether the building surface is a flat surface or a curved surface, the arc-shaped clamping plate 331 or the flat clamping plate 332 can be specifically selected to meet the requirement of being fixed on a special-shaped building;

[0045] 5. By arranging a mounting block 22 on the limiting column 2 to fill the gap of the strip groove 11 where the adjusting rod 1 is installed, the connection strength between the limiting column 2 and the adjusting rod 1 can be improved.
